What is affinity bias?

Affinity bias, also referred to as similarity bias, is the unconscious human tendency to gravitate toward other people with similar backgrounds, interests, and beliefs. While we may think that we actively make conscious choices to surround ourselves with people based on their character, the reality is that we aren’t very good at being objective when choosing who we like and want to be around.

What causes affinity bias?

First, being around others like ourselves is affirming. We’re more likely to hear our opinions and thoughts echoed and upheld, giving us a sense of validation. Similarly, affinity bias allows us to avoid confrontation with other, different points of view that we may find challenging to accept.

What are some examples of affinity bias?

There are many ways in which affinity bias can sneakily show up in your thinking. For example, you might assume that a person is well-educated because they went to the same university as you or that somebody is qualified for a role because they previously worked at the same company you did.

What’s the connection between affinity bias and diversity and inclusion?

One important thing to consider is how affinity bias can affect your organization’s DEI&B. Because when recruiters and leaders are always hiring, promoting, and nurturing people similar to themselves, it creates a workforce full of people of the same backgrounds, destroying diversity.

Why should modern HR teams be aware of affinity bias?

We can’t control the unconscious biases we naturally hold as human beings. But when they can negatively impact our organization’s culture, inclusivity, and success, it becomes our duty to learn how to mitigate affinity bias. Taking active steps toward dismantling our own internal biases will ultimately make for better, more strategic decision-making and a more equitable workplace.
